Answer

Answer

Thoracic zygapophyseal joint blocks have received little attention in the literature. The orientation of these facet joints does not lend them to the posterolateral approaches used for intra-articular injections as in the cervical or lumbar spine. Furthermore, the exact course of the medial branches of the thoracic dorsal rami and the pattern of innervation of these joints has not been researched adequately.
